Flexible supercapacitors with high charge storage ability are needed for emerging applications in wearable
electronics. Here, we introduce a novel flexible supercapacitor electrode by incorporating flower-like MoS2 into
MXene via a hydrothermal technique. We mostly focused on the structural design for electrode configuration to
enhance the charge storage mechanism. Three different electrodes composed of MoS2, MXene, and MoS2@MXene were fabricated via a versatile drop-casting and drying method. There are unique advantages of incorporating MoS2 with MXene such as the fast electron transfer, hydrophilicity of the interface, and structural stability.
The MoS2@MXene // MXene flexible asymmetric supercapacitor device offered a high energy density of 1.21 W
h /kg and a power density of 54.45 W /kg. Moreover, the asymmetric device exhibits nearly identical electrochemical behavior following 100 bending cycles at different angles. The high electrochemical activity of MoS2
and MXene and good interaction are ascribed to the superior electrochemical performance of the composite
material. Furthermore, this research could guide the development of flexible, high-performance, and low-cost
electrodes which will be useful in wearable electronics.
